Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If bandwidth part activation is performed without considering transmission parameter requirements, then activation speed is improved, but transmission quality and interference control deteriorate
Solution Approach 1:
The system performs preliminary determination of transmission parameter requirements before BWP activation. The capability to configure transmission parameters is assessed in advance, and additional requirements are identified prior to activation, ensuring that the BWP is activated with appropriate parameters already prepared, thus maintaining both speed and quality.
Solution Approach 2:
The patent dynamically adjusts transmission parameters based on determined capabilities and requirements. By changing parameters such as filter bandwidth and local oscillator placement according to the specific BWP configuration needs, the system achieves efficient activation while maintaining transmission quality and reducing interference.
2Reliability
If transmission parameters are configured with additional requirements, then emission compliance is improved, but activation time increases
Solution Approach 1:
Additional requirements for transmission parameters are determined in advance before activation. By pre-identifying what additional parameters need to be configured (such as specific filter bandwidths or LO placements), the system can proceed directly to activation without time-consuming on-the-fly calculations, thus minimizing activation time while ensuring compliance.
Solution Approach 2:
The system efficiently manages parameter changes by having pre-determined capability information about which parameters can be adjusted. This allows the system to make necessary parameter modifications for emission compliance through straightforward configuration rather than complex real-time adjustments, reducing the time impact.
3Adaptability or versatility
If different transmission parameters are used for different BWPs, then adaptability to different scenarios is improved, but system complexity increases
Solution Approach 1:
The system segments the BWP configuration process into distinct steps: determining capability, identifying additional requirements, and then activating with appropriate parameters. This segmentation allows different scenarios to be handled through a standardized, modular approach, reducing overall system complexity while maintaining adaptability.
Solution Approach 2:
The patent creates a universal determination process that can handle various BWP scenarios through a single consistent methodology. By using a general framework for assessing capabilities and requirements, the system achieves multi-functionality across different scenarios without requiring separate complex handling for each case.
